Sharp claws are pointed, curved structures found at the end of the toes of many animals, including cats, birds, and reptiles. They are made of a hard protein called keratin and serve various purposes, such as hunting, climbing, and defense. Sharp claws can help animals grip surfaces and catch prey effectively. In addition to their functional uses, sharp claws can also play a role in communication and social interactions among animals. For example, some species may display their claws to assert dominance or attract mates. Overall, sharp claws are essential tools for survival in the wild.
